Mainspring Replacement
Send us your clock barrel for our Hole-End Mainspring Replacement Service. We will swap out the mainspring for a new one. The price for this service includes the cost of the mainspring. When you check out online, you will be paying for return shipping to get the barrel back to you.
The Process
With the Hole-End Mainspring Replacement Service, we will take the broken or worn mainspring out of the barrel in a safe way. Next, the measurement of the thickness and width of the spring is taken. To get the correct length, we have to stretch out the old spring and measure that as well. So the final step is to take those measurements and match them up to the chart.
This ensures the correct spring will be put into the barrel. So, the next step is the actual installation of the spring. The use of a mainspring winder enables a secure and tight fit into the barrel. After that your new spring will be on its way back to you.
We highly recommend using our Hole-End Mainspring Replacement Service because mainsprings can be very dangerous. We have the appropriate tools, and the knowledge, to get it done correctly. The power in these springs has the capability to cut fingers.
So utilizing this service makes for a quick and painless repair. Thus making your clock able to be back up in running in no time. Of course, if you ever have any questions about this process please feel free to ask.
I have a Howard Miller wall clock Model No. 612-578. it has 3 spings in it. The one that makes the clock run is broken. It is in a barrel. Is this something you could fix?
What are the numbers off of the back plate of the clock movement itself? If it is hard to get to, usually you can stick a cell phone up behind the movement and get a picture of the numbers. Or through the side access panel if there is one.

The mainspring in an old German pendulum wall clock has broken (I guess). It winds freely. How do I get to it, to send it to you for replacement/repair? The movement has the numbers 34/116 and 5181. Any suggestions? Thanks
Can you visually see the mainspring or is the spring enclosed inside a barrel cover? Is the barrel removable by you, to send it in for mainspring swap? The cost for this service is $100 and includes the cost of the mainspring itself

I have a Seth Thomas pre 1950, that I think the mainspring is broken. This is my first attempt at clock repair so I admit ignorance. The spring is housed in a totally enclosed “barrel”. Is that something you guys can repair/replace?
Yes please send the barrel in with the mainspring still inside.
Please let us know its coming by filling out the repair form at this link
